Convert the AC input into a two different DC outputs
Input AC peak voltage: 1 – 9 V
Input AC peak current: 38 – 348 mA
Frequency: 20 – 150 Hz
Output 1 -> DC Voltage: 3.3 V
Current: 100mA
Output 2 -> DC Voltage: 5V
Current: suitable for two LM35 thermistors. (Current requirement for this sensor is 100uAmp. If biased properly)
There will be provision for charging the lithium ion battery with automatic cutoff and charging (as discussed in email).
- Components will be thru hole and SMT (as the capacitors need to have long life span).
- Connectors (for temperature sensors) used on PCB will be easy to find and will be easy to mount.
- Power Connector will be screw mounted and easy to find.
- We will send a DXF (cad format file) file or something equivalent to let you to look the design and choose the final dimensions of the layout. In every case we will keep the pcb dimensions small so that it is cheap in production.
- We will include a BOM with part numbers from Mouser (or Arrow, or another worldwide dealer). For the quantity of 10,100 and 1000 pieces.
- Comparative statement will be generated to select the lowest bidder.
- The final design must be ready to send to a mass manufacturer to build it.
